COVER INFORMATION Station: IRBENE (Code Ir ) Experiment: Characterizing OCRs in dwarf galaxies Exp. Code: ev026g Schedule Version: 2.00 Processed by SCHED version: 11.60 Release 11.6; April 2020 PI: Dany Vohl Address: Anton Pannekoek Institute for Astronomy, University of Amsterdam 1098 XH Amsterdam Amsterdam The Netherlands Phone: +31 6 1887 9982 EMAIL: d.vohl@uva.nl Fax: Phone during observation: +31 6 1887 9982 Observing mode: vlbi Notes: # Please, make sure PHASE CAL is OFF # COVER LETTER: This observation is to observe ILT ILTJ231715.38+184339.0 first identified in the LoTSS DR2 data as potential analogue to persistent radio sources associated to some fast radio bursts. With the observation, we wish to constrain it s source size, and evalute if the radio emission is due to star formation processes or not.

SCHED provides warnings at individual scans for distances less than 10 degrees. The distance from the Sun to each source in this schedule is: Source Sun distance (deg) ILTJ2317 71.5 B2319+60_D 64.3 J2236+2828 77.5 J2253+1608 77.5 J2320+1829 70.7 Barry Clark estimates from predictions by Ketan Desai of IPM scattering sizes that the Sun will cause amplitude reductions on the longest VLBA baselines at a solar distance of 60deg F^(-0.6) where F is in GHz.
